STI STI-1221A4X-WD Strobe Damage Stopper and Enclosure Back Box
Overview
The STI-1221A4X-WD is a Type 4X stainless steel enclosure back box paired with a strobe damage stopper — designed to shield visual alarm notification devices from impact, weather, and corrosive environments. This unit protects strobe signaling components in outdoor security installations, marine facilities, and high-traffic areas where accidental or intentional contact could disable the device. The 4-inch depth and stainless construction meet NEMA Type 4X requirements for salt-fog, washdown, and coastal exposure scenarios. Commonly deployed in access control notification systems where visual alarms must remain operational despite environmental stress.
Compatibility
This enclosure back box integrates with STI strobe warning systems and visual notification appliances used in security control infrastructure. Compatible with standard 4-inch-depth mounting configurations in access control and life safety notification applications. Suitable for integrators deploying visual alarm devices in harsh environments including marine, industrial washdown, corrosive chemical, and high-traffic facility settings where Type 4X stainless steel enclosure construction is required by code or application demand.
Installation Notes
Frame assembly dimensions: 8.5 inches (216 mm) height, 6.5 inches (165 mm) width, 3.5 inches (89 mm) depth. Four #8-32 x 3/8-inch socket head cap screws and four Rawl plugs provided for wall mounting. Standoff blocks (quantity 2) included for installations requiring washdown protection. Optional conduit hub (3/4-inch rigid conduit) accepts an enviro kit when frequent washdowns occur — order separately if environmental exposure dictates sealed wiring access. Back of frame assembly may be drilled to accommodate added wire protection due to environmental conditions. Installation must comply with applicable NEC, NFPA, and local codes.
